2 Claims.

Thisf invention relates to trays and I'boxes.

The'primarymbjectofthe invention iswto provide atray or` box-for the.handling of merchandise, particularly inA bakeries-for thedelivery ofbread, cake.. doughnuts; cookies and the like bakeryy products,l andwhich -boxis light; easy` to handle and .to stack rand issanitary.

Thefeatures of our invention :are:

A" light'.skeletonv frame: and i a liningA of= nbreboard or.thelikerheld in the skeleton frame so asrto be easily* replaceable"` andthus.` combining lightness, durability and facility toikeep the: tray insanitary condition; a light lining preferably ofbreboa-rd whichcanbestored and 'shipped in collapsed-atfpositioniand' which can vbeextended to fit into the frame of the tray so as to be prevented'fromcollapsing while in use; a rim or top edge structure which has a limitedresiliencyjand which provides a' projection for engagementwith the topedges ofthe sides of the lining .orjremovable` walls;y integralelementson the skeleton frame to facilitate interlocking and stacking; easyadaptation for'various usesr and retaining the facility of'replacing ofthe inserts;

We are awarethat'some changes may be made in the general arrangementsandcombinations. of the several'devices andparts,' aswellga's-V in thedetails ofthe constructionthereof withoutdeparting from thescope ofthepresent invention as set' forth in thefollowing speci'cationandas frameof the tray constructed in accordance with our invention.

Fig. 8 isa liragmental sectional vievvof the tray viewing =a cornerthereofl In carrying out our invention we make use of a skeleton frame Iand a light andi disposable insert 2.

The skeleton frame; in theA form illustrated in Fig. 1, is particularlyadapted: for use as a bread box, arrditincludesvhorizontal*bottom pieces3. Each bottom pieceA 3f is of substantially. angle constructionso astoprovde a bottomvlange 4 and an upright side-flanged. 'lhese bottompieces are suitably secured, preferably by spot Welding, to the lowerends of vertical corner-'bars 1. Each vof these corner bars i" ispreferably of angle around-'a wire orl rod II; which latter is formedinto a rectangular shape parallel with the rec- "ta-ngular shape'denedby the bottom pieces 3. lThe strip offsheet metalthus forms aV tubularwrappinglz around said `wire l I, and it also forms a skirt I3 whichextends downwardly from said tubular wrapping I2 and is preferably spotwelded to the top portions of the vertical corner bars 1. The rim thusformed 'by the tubular wrapping I2 and the Wire II overhangs or overlapsinwardly of the basket to form a ledge I4 projecting over and above thebottom anges 4 of the respective bottom pieces 3. The insert 2 ispressed under said ledge I4 and is maintained in its upright position.

At each end of the cross bar 9 extends upwardly a vertical brace I6between the upright flange 6 and the skirt I3.

The skirt I3 at the middle of each end of the tray is folded underinwardly so as to form a rounded grip I1 for the handling of the tray.At each end of the grip I'I is a vertical thumb brace I3 between therespective upright anges 6 and portion of the skirt I3.

The cross bar 9, the brace I6 and thumb braces I8 are formed of thecross section shown in Fig. 3, namely are 'dished so as to form a rib I9outwardly of the tray thereby to increase the rigidity of the brace.

The insert 2 is preferably made of fbreboard. It includes a bottom 2|.At the longitudinal edges 22 of the bottom are side flaps 23 which arefoldable up into the position shown in Fig. 4. At each end edge 24 ofthe insert bottom 2l is an end iiap 26 which is foldable up into theupright position between the ends of the side flaps 23. Each end ap 26is cut away at the middle of its top edge to form a grip recess 21 whichis located opposite the grip I1 at the end of the tray l. The insert isstored in a flat position, namely the end flaps 26 are folded over thebottom 2l and then the side flaps 23 are folded inwardly. This foldedflap is placed into the tray so that the insert 2| rests upon the bottomflanges 4. Then the side flaps 23 and end flaps 26 are unfolded andpressed under the respective ledges I4 to be held in place. The heightof the side aps 23 and end flaps 26 is such that they t tightly orsnugly between the bottom flange 4 and the adjacent ledge I4. Thus theledge I4 effectively holds the insert 2 in place when an empty tray isturned upside down, or when in handling a full tray upward pressure isapplied to the bottom 4.

For facilitating stacking of the trays, We illustrate in Figs. 1, 5, 6and 7 the use of generally triangular corner projections 28 at eachcorner of the tray I. These projections are formed by a generallytriangular hollow boss with outwardly extended flanges 29 at each edgethereof which latter are welded to the underside of the bottom flanges 4at each corner of the tray. The triangular corner projections 28 are soarranged that the right angle sides thereof are spaced inwardly from andparallel with the adjacent sides at the corner of the tray so that whena tray is superimposed upon another, then the corner projections 28 fitinto the corners of the top section of the lower tray and prevent theaccidental sliding of one tray olf the other.

Another form of stacking projection is illustrated in Fig. 2 and is inthe form of ribs 3l pressed downwardly out of the bottom fianges 4 allaround the tray I.

We claim:

l. A tray of the character described comprising a base frame, generallyvertical corner post members extended from the base frame, a top frameon the tops of said vertical corner post members, a disposable liningfitting into the area dened by said frames, and a generally cylindricalsolid rim element on said top frame projecting inwardly of the tray andabove the adjacent edges of the lining, said lining including a bottomand sides foldable from a collapsed position over said bottom to anupright position between said base frame and said rim, the spacingbetween the base frame and said rim being such as to snugly receive saidsides of the lining therebetween so as to hold said sides in uprightposition.

2. A tray of the character described comprising a base frame, generallyvertical corner post members extended from the base frame, a top frameon the tops of said vertical corner post members, a disposable liningfitting into the area defined by said frames, and a continuous retainingrim element all around said top frame, said lining including a bottomand sides foldable from a collapsed position over said bottom to anupright position between said base frame and said rim element, said rimelement extending inwardly of said tray overlying the top edges of saidlining sides and being spaced from said base frame to such an extent asto snugly receive said lining sides therebetween so as to hold saidlining sides in upright position, the lining sides at two opposite sidesof the tray having handle recesses at their tops, and upright handlebraces between the bottom frame and the top frame adjacent each side ofsaid recesses spaced to serve as thumb rests.
